BCT4157是一款Low-Voltage, 2.8Ω SPDT analog Switch
The BCT4257 is a high -bandwidth, fast single pole double-throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the BCT4257 has a maximum ON resistance of 5.1-ohms at 1.65V, 3.9-ohms at 2.3V & 2.85-ohms at 4.5V.
Break-before-make switching prevents both switches being enabLED simultaneously. This eliminates signal disruption during switching.
The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage. BCT4257 is an improved direct replacement for the 74LVC1G3157.

The BCT4157/4157B is a high- bandwidth, fast single-pole double-throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the BCT4157/4157B has a maximum ON resistance of 5 .1 -ohms at 1.65V, 3.9 -ohms at 2.3V & 2 . 85 -ohms at 4.5V.
Break-before- make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.
The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage. BCT4157/4157B is an improved direct replacement for the FSA4157/NC7SB4157
